Antireflux mucosectomy for managing reflux symptoms in an obese patient post laparoscopic sleeve gastrectomy.

Laparoscopic sleeve gastrectomy (LSG) is an effective treatment modality for obesity. Commonest delayed complication post LSG is gastroesophageal reflux disease (GER). The prevalence of GER among obese patients is higher than normal individuals. Such patients need long term Proton pump inhibitors (PPI) or antireflux procedures to manage reflux. Antireflux mucosectomy (ARMS) uses techniques of endoscopic mucosal resection to treat reflux for PPI refractory GER. However, it can be technically challenging to perform ARMS with a restricted stomach in patients who have undergone LSG. A 40-year-old female, hypertensive who had previously undergone LSG was treated for GER by a multidimensional approach with ARMS utilizing hypotensive anesthesia. The patient underwent the procedure successfully without any complication. She was discharged and at follow up visit, her reflux symptoms had improved and endoscopy was unremarkable. We describe this unusual case which was treated effectively with ARMS.

Postgastrectomy Syndromes and Nutritional Considerations Following Gastric Surgery.

Postgastrectomy syndromes result from altered form and function of the stomach. Gastrectomy disrupts reservoir capacity, mechanical digestion and gastric emptying. Early recognition of symptoms with prompt evaluation and treatment is essential. Many syndromes resolve with minimal intervention or dietary modifications. Re-operation is not common but often warranted for afferent and efferent loop syndromes and bile reflux gastritis. Preoperative nutritional assessment and treatment of common vitamin and mineral deficiencies after gastrectomy can reduce the incidence of chronic complications. An integrated team approach to risk assessment, patient education, and postoperative management is critical to optimal care of patients with gastric cancer.

Impaired Gastrointestinal Function Affects Symptoms and Alimentary Status in Patients After Gastrectomy.

BACKGROUND: Postgastrectomy syndrome (PGS) remains a common complication after gastrectomy that affects patients' quality of life. Although impaired gastrointestinal (GI) function by gastrectomy procedures is thought to be the cause, the precise pathophysiology of PGS is yet to be clarified. AIM: The aim of this study was to investigate relationships between GI function and various symptoms or alimentary status in patients after gastrectomy. METHODS: Fifty-one patients who underwent total or distal gastrectomy at least 1 year previously were studied. All patients replied to a questionnaire that asked presence of symptoms (esophageal reflux, nausea, abdominal pain, early satiation, diarrhea, early dumping general, early dumping abdominal, and late dumping symptoms) and alimentary status (change in body weight, food intake per meal, frequency of meals per day). They also underwent assessment of GI function consisting of gastric emptying study by 13C-acetate breath test to examine reservoir capacity and gastric emptying, and water load drink test to evaluate tolerance to volume loading (TVL). The relationships between GI function and each symptom or alimentary status were examined. RESULTS: The patients with nausea and early dumping general symptoms had significantly smaller reservoir capacity*, the patients with diarrhea and early dumping general symptoms had significantly faster gastric emptying*, and the patients with early satiation and early dumping abdominal symptoms had significantly impaired TVL*. Significant correlations were identified between TVL and body weight changes* or food intake per meal* (* p < 0.05). CONCLUSION: Impaired postoperative GI function was closely related to symptoms or worse alimentary status.

[THE DIGESTIVE TRACT MOTILITY AND NUTRITIONAL SUPPORT WITH POSTGASTRORESECTIONAL SYNDROME].

The variety of clinical manifestations operated stomach fits in the sequence of pathological syndromes: dumping and hypoglycemic syndromes, postgastroresectional post gastrectomy anemia, afferent loop syndrome, postoperative dystrophy, reflux esophagitis, a syndrome of "small" stomach, and hypoglycemic syndrome. Aim--to elucidate the role of disorders of motor function of the gastrointestinal tract in postgastroresectional syndromes and their correction. The nutrient administration reduced a motor function level of the stomach, restore motor function of the duodenum and ascending colon intestine, normalize ino- and chronotropic relations in the smooth muscles of the sigmoid colon.

[Surgical treatment of type 2 diabetes mellitus]. / Tratamiento quirúrgico de la diabetes mellitus tipo 2.

Sustained remission of type 2 diabetes mellitus and significantly improved hyperlipidemia and arterial hypertension, control has been achieves in both lean and obese patient after bariatric surgery procedures or other gastrointestinal surgical procedures. It has been demonstrated that the metabolic effects of bariatric surgery in these patients derives not only in reducing weight and caloric intake, but also endocrine changes resulting from surgical manifestation gastrointestinal tract. In this article we review the clinical outcomes of such interventions (collectively called "metabolic surgery") and the perspectives on the role that these surgeries play in the treatment of patients with type 2 diabetes mellitus.

Diversos procedimientos de cirugía bariátrica y otros quirúrgicos gastrointestinales pueden remitir la diabetes mellitus tipo 2 y disminuir la hiperlipidemia e hipertensión arterial en pacientes obesos y no obesos. Está demostrado que en esos pacientes los efectos metabólicos de la cirugía bariátrica no sólo se reflejan en pérdida de peso e ingesta calórica, sino también en cambios endocrinos resultantes de la manifestación quirúrgica del tubo gastrointestinal. Se revisan los resultados clínicos de esas intervenciones ("cirugía metabólica") en pacientes con diabetes mellitus tipo 2 y las perspectivas de su papel en el tratamiento de la diabetes mellitus tipo 2.

[State of duodenal patency in patients with postgastrectomy syndromes].

It was analyzed the examination and treatment results of 100 patients who underwent resection of stomach by Billroth-I in case of peptic ulcer. Chronic disorders of duodenal patency were diagnosed in 86% of patients. The main role of chronic disorders of duodenal patency in postgastrectomy syndromes development was proved. There were a combination of reflux gastritis with dumping syndrome in 66.3% of patients, a combination of reflux gastritis with recurrent ulcer in 8.1% of patients. Correction of chronic disorders of duodenal patency is necessary stage in conservative and surgical treatment of postgastrectomy syndromes.

Assessment of motor function of the remnant stomach by ¹³C breath test with special reference to gastric local resection.

BACKGROUND: Indications for gastric local resection (LR) include gastrointestinal stromal tumors, neuroendocrine tumors, and early gastric cancer. LR is expected to preserve physiological function and ameliorate postgastrectomy syndrome. METHODS: Gastric emptying was assessed by the (13)C-acetate breath test in 20 healthy volunteers (HVs) and 60 gastrectomized patients [distal gastrectomy with Billroth I reconstruction (DGBI) in 26 patients, LR in 34 patients]. For the (13)C breath test, 100 mg of (13)C-acetate sodium salt was mixed in a test meal. Breath samples were collected before intake and during the next 3 h. We compared the gastric reservoir capacity using the gastric retention rate at 5 min (RR5) and gastric emptying by the half emptying time (T½). Patients completed a questionnaire survey about their symptoms, dietary intake, body weight, and restriction of activities of daily living [reflecting quality of life (QOL)]. RESULTS: The RR5 values for the HV, LR, and DGBI groups were 93.7, 90.0, and 45.3* %, respectively (*compared to HV and LR, p < 0.0001). The T½ values were 23.3, 20.2, and 5.9* min, respectively. Dietary intake and body weight change were significantly more reduced in the DGBI group than the LR group (p < 0.05). Subgroup analysis indicated that the reservoir capacity in those with LR at the lesser curvature was more disturbed than that in patients with LR at the greater curvature. The questionnaire showed no differences in those patients' QOL. CONCLUSIONS: Because the reservoir capacity, the gastric emptying and QOL were maintained, LR is an option for selected patients with early gastric cancer.

Bariatric and metabolic surgery.

In the beginning of the 21st century obesity still represents health, social and economical threat for most of economically wealthy countries worldwide. Estimated direct costs for obesity and related comorbidities treatment exceed 5% of the total health care costs both in the US and in European Union. However, in addition there are obesity-related indirect costs linked to more frequent work sickness leave, higher unemployment rates and overall lower productivity of obese patients. Surgical treatment of obesity (bariatric surgery) is the most effective long-term treatment modality for those patients suffering from higher degrees of obesity. Bariatric surgery has not only positive effects on weight loss, but is also extremely effective in improving or resolving many of obesity-related comorbidities, which have evolved rapidly into the so-called metabolic surgery. T2DM may serve as excellent example of metabolic, obesity-related comorbidity which can be treated with bariatric-metabolic procedure even without direct relation to weight loss. In such cases bariatric surgery evolves into metabolic surgery. Thus metabolic operations (namely from the malabsorptive end) deeply influence hormonal secretion especially in the proximal part of small bowel, change parametres of entero-insular axis and have positive influence on insulin secretion, sensitivity and on the entire complex of glucose tolerance. Nowadays we can witness dramatic changes in perception of T2DM from bariatric surgeons, diabetologists, and many other medical specialists. T2DM has evolved from primarily medical disease into a condition where surgeons may play a more active role in the management of the diabetic patient. However, it has to be stressed that metabolic treatment of T2DM and other metabolic disorders need multidisciplinary approach and collaboration and that surgeon should play very important role as a multidisciplinary team member, however metabolic surgery should not yet be considered as stand-alone treatment modality.

[The substantiation of the method of gastrointestinal reconstruction after the gastric resection].

Functional results of 289 major gastric resections and gastrectomies were analyzed. New methods of the gastrointestinal reconstruction after these procedures. The comparative analysis of immediate and long-term results allowed to work out criteria of choice for the reconstructive procedure. Benefits of the suggested reconstructive techniques demonstrated with the use of modern diagnostic means.

[The role of chronically disordered duodenal patency in the development of post-gastroresection syndrome].

We assessed results of examination and treatment of 100 patients with ulcer disease who had undergone Bilroth-1 stomach resection. Chronic disorder of duodenal patency was revealed in 86% of the patients. This condition was shown to play the leading role in the development of post-gastric resection syndrome. Reflux-gastritis was associated with damping syndrome in 66.3% of the patients and with recurrent ulcer in 8.1%. It is concluded that conservative and surgical treatment of post-gastric resection syndrome should be aimed at correction of chronic disorders of duodenal patency.

[Improving the quality of life after gastrectomy is the next issue after saving the lives of patients with gastric cancer].

Gastrectomy saves the lives of many patients with gastric cancer. However, this surgical treatment is associated with clinical problems called postgastrectomy syndrome (PGS) which affect the quality of life (QOL) of such patients. For surgeons, improving the QOL after gastrectomy is an important goal after performing curative surgery. In the clinical setting, various surgical procedures such as limited resection, function-preserving procedures, and reconstruction using gastric substitutes have been advocated to reduce the severity of PGS. However, the actual conditions and pathophysiology of PGS have not been fully investigated. Various clinical studies and basic research have partially clarified the features and pathophysiology of PGS, although the strategies developed to treat PGS have been limited. The development of standardized, reliable instruments for understanding PGS and performing large-scale collaborative studies are required to improve the diagnosis and treatment of PGS. In Japan, such a project called the PGSAS has recently been completed. The results are being analyzed and will be reported in the near future.

Effects of emptying function of remaining stomach on QOL in postgastrectomy patients.

BACKGROUND: Attention has recently focused on decreased quality of life (QOL) that occurs in postgastrectomy patients. We verified how gastric emptying function affected QOL. METHODS: Subjects were 72 consecutive patients after gastrectomy for cancer, including 25 after distal gastrectomy (DG), 18 after proximal gastrectomy (PG), 16 after pylorus-preserving gastrectomy (PpG), and 13 after total gastrectomy (TG). Using the (13)C breath test method, (13)CO(2) levels in breath were measured over 2 h, and T (max) was determined. Questionnaires (Japanese versions of the Short-Form 36 [SF-36] and Gastrointestinal Symptom Rating Scale [GSRS]) were used to analyze QOL and correlations between questionnaire results and T (max). RESULTS: Mean T (max) (min) for each procedure was 15.4 for DG, 21.1 for PG, 41.3 for PpG, and 10.4 for TG. T (max) differed between procedures, but not between survey periods. SF-36 was not correlated with T (max), whereas GSRS showed a difference in diarrhea and total score between procedures, but not between survey periods. In addition, GSRS correlated with T (max) for abdominal pain, indigestion, and total score. The total scores showed a significant symptom aggregation in patients with T (max) less than 21 min. CONCLUSIONS: Gastrointestinal symptoms in postgastrectomy patients were associated with the function of the remaining stomach. The (13)C breath test is useful for objectively assessing such symptoms.

Postoperative long-term evaluation of interposition reconstruction compared with Roux-en-Y after total gastrectomy in gastric cancer: prospective randomized controlled trial.

BACKGROUND: The postoperative clinical superiority of the interposition of jejunum reconstruction (INT) to Roux-en-Y reconstruction (RY) after total gastrectomy has not been clarified. Postoperative quality of life (QOL) was evaluated between the 2 methods by a multi-institutional prospective randomized trial. METHODS: A total of 103 patients with gastric cancer were prospectively randomly divided into groups for RY (n = 51) or INT reconstruction (n = 52) after total gastrectomy. They were stratified by sex, age, institute, histology, and degree of lymph node dissection. Postoperatively, body mass index (BMI) and nutritional conditions were measured serially, and QOL and postoperative squalor scores were evaluated at 3, 12, and 60 months and compared between the 2 groups. RESULTS: After removing patients who did not complete the follow-up survey or censured cases, 24 patients in the RY group and 18 patients in the INT group were clinically available and their postoperative status was assessed. QOL scores were increased and complication scores were improved in the postoperative periods (P < .01). Postoperative BMI significantly deteriorated compared with preoperative BMI in each group. The postoperative QOL and complication scores at 60 months after surgery were significantly better than those at 3 months after surgery in each group (P < .01). However, there was no significant difference of QOL scores and postoperative complication scores between the 2 reconstruction groups. The nutritional condition in the INT group was nearly the same as that in the RY group. CONCLUSIONS: Although our patient sample was small and patients who did not complete the follow-up survey were present, we could not identify any clinical difference between INT and RY after total gastrectomy 60 months after surgery. The safer and simpler RY method may be a more suitable reconstruction method than INT after total gastrectomy.

[Postgastrectomy syndromes in therapeutic practice ].

AIM: To specify policy of nutritive support late after radical gastric resection. MATERIAL AND METHODS: Patients with postgastroresectional dystrophy were examined using standard techniques and estimation of intestinal electric activity (registration of body surface biopotentials on Conan-M myngograph). RESULTS: Frequency-amplitude parameters of the intestine serve the basis for choice of mixtures for enteral correction. Nutritive support provided for on demand pharmaconutrients--microbiotic correctors. CONCLUSION: Myography gives additional information for decisions on the policy of nutritive support.

Correlation between the length of the pyloric cuff and postoperative evaluation after pylorus-preserving gastrectomy.

BACKGROUND: Recent years have seen the preserved pyloric cuff being lengthened in pylorus-preserving gastrectomy for early gastric cancer. We performed clinical assessment of the symptoms after pylorus-preserving gastrectomy in patients treated at the National Cancer Center Hospital in Japan during the past 9 years. METHODS: Four hundred and fifty-six patients who had undergone pylorus-preserving gastrectomy and been followed up for at least 3 years were studied. We classified the patients into two groups according to the length of the pyloric cuff (group A, within 3.0 cm; group B, more than 3.0 cm). Medical records were reviewed for further histological and follow-up data. A questionnaire regarding dumping syndrome and gastric stasis was also completed by the patients. RESULTS: Our results showed no statistically significant differences in symptoms, such as dumping syndrome or emptying disturbances, between the two groups. CONCLUSION: Our study revealed that the differences in several functions and symptom scales were not pronounced between the two groups. Regardless of the length of the pyloric cuff, pylorus-preserving gastrectomy can be utilized for the treatment of early gastric cancer even if the tumor is located proximal to the middle body.

Gastric emptying function in patients 5 years after pylorus-preserving distal gastrectomy with or without preserving pyloric and hepatic branches of the vagal nerve for early gastric cancer.

BACKGROUND: To clarify the significance of preserving pyloric and hepatic branches of the vagal nerve (PHV) after pylorus preserving distal gastrectomy (PPG) for early gastric cancer, the author investigated the postgastrectomy syndrome and gastric emptying function at 5 years in PPG patients with or without preserving the PHV. METHODS: A total of 18 subjects (mucosal cancers) who underwent PPG with D1 lymph node dissection and preserving the PHV; they comprised group A-12 men and 6 women aged 38-68 years (mean 58.9 years). They were interviewed to inquire about gastrointestinal symptom (appetite, weight loss, gastric fullness, reflux esophagitis, early dumping syndrome) and then were compared with 24 PPG patients (submucosal cancers) with D2 lymph node dissection without preserving the PHV (group B-16 men and 8 women aged 33 to 69 years, mean 60.1 years). Esophagogastric endoscopy, abdominal ultrasonography, and gastric emptying function tests (GET) were undertaken, the latter by both radioisotope (solid diet) and acetaminophen (liquid diet) methods. RESULTS: There were no differences in the postoperative gastrointestinal symptoms, endoscopic reflux esophagitis, or endoscopic mucosal edema and redness (gastropathy) between groups A and B. However, more cholecystolithiasis (gallbladder stones) was found in group A than in group B, with the difference being significant (P < 0.0391). The GET for solid diet and liquid diet were the almost same among groups A and B. CONCLUSIONS: There were no significant differences in the postoperative QOL and GET between PPG patients with preserving PHV and those without preserving PHV. Cholecystolithiasis was only found in patients without preserving PHV.

The influence of reconstruction methods on food retention phenomenon in the remnant stomach after a subtotal gastrectomy.

BACKGROUND AND OBJECTIVES: Food retention and bile reflux has been frequently observed in gastric cancer patients following a subtotal gastrectomy. The aim of this study was to determine whether reconstruction methods after the distal subtotal gastrectomy influenced the degree of food residue and bile reflux. METHODS: The prospectively collected data was reviewed retrospectively for 522 patients with early gastric cancer who had undertaken a follow-up endoscopic examination after a distal subtotal gastrectomy between 2003 and 2006. RESULTS: The incidence of food retention was 55.5%, 31.9%, and 20.9% at 3, 12, and 24 months after distal subtotal gastrectomy, respectively. The food residue score was higher in the Billroth I (stapling) group than the Billroth II (hand sewing) group at 3 months after surgery (P = 0.006). The incidence of bile reflux was higher in the Billroth II group than in the Billroth I group at 12 and 24 months after surgery (P < 0.001, P = 0.002, respectively). No significant association was found between the food retention and body weight changes. CONCLUSIONS: Food retention was detected in lots of patients after subtotal gastrectomy and the reconstructive methods after subtotal gastrectomy was not relevant to food retention.

Symptom evaluation of long-term postoperative outcomes after pylorus-preserving gastrectomy for early gastric cancer.

BACKGROUND: Since the early 1990s, pylorus-preserving gastrectomy (PPG) has been used in the treatment of patients with early gastric cancer in order to reduce postprandial symptoms. To date, there have been few reports of long-term symptom evaluation following this procedure. The aim of this study was to evaluate long-term postoperative outcomes after PPG. METHODS: Three hundred and ninety-seven patients with early gastric cancer were enrolled in this study: 194 patients who underwent PPG and 203 who underwent distal gastrectomy with Billroth-I reconstruction (DGBI). We compared the symptoms for the two groups in a questionnaire on postoperative functional outcomes, endoscopy findings and the appearance of gallstones after surgery. RESULTS: The incidence of symptoms suggesting early dumping syndrome was significantly lower in the PPG group compared with the DGBI group (P < 0.05). The incidences of disturbed bowel habit and frequent flatus were significantly lower in the PPG than in the DGBI group. The average relative body weight (actual BW/ BW immediately before the surgery) was significantly better in the PPG than in the DGBI group (P < 0.001). CONCLUSION: The long-term results show that PPG has clear advantages over DGBI in terms of postoperative symptoms and functional outcomes. These results imply that PPG should be the recommended procedure for early gastric cancers located in the middle third of the stomach.

Roux-en-Y or 'uncut' Roux procedure? Relation of intestinal migrating motor complex recovery to the preservation of the network of interstitial cells of Cajal in pigs.

We designed a conscious pig model to investigate myoelectric activity and the number of interstitial cells of Cajal (ICC) in the proximal jejunum following the Roux-en-Y and 'uncut' Roux procedures in relation to clinical outcomes. Twelve male Polish White pigs (8 weeks old, 10-13 kg) underwent surgery under general anaesthesia first to implant bipolar electrodes and telemetry transmitters for continuous electromyography recordings and then, after 1 week recovery, to create Roux-en-Y (n = 6) and 'uncut' Roux loops (n = 6). Upper gut tissue specimens were studied for the expression of c-kit staining procedure to quantitatively identify the presence of interstitial cells of Cajal. The intestinal migrating motor complex was restored within 10.5 and 37 h in 'uncut' Roux and Roux-en-Y pigs, respectively (P < 0.05). During 2 weeks, the 'uncut' Roux piglets increased their body weight by 18.0%, whereas the Roux-en-Y piglets increased their body weight by only 7.3% (P < or = 0.05). Two weeks after surgery, the number of ICC located in the region of Auerbach's plexus was higher and adhesions in the abdominal cavity lower in the 'uncut' Roux group. In conclusion, in the pig model, preservation of smooth muscle and ICC network continuity in the proximal jejunum may play an important role in early postsurgical recovery.
